The U.S. Federal Trade Commission has weighed in on the contentious issue of the proposed sale of consumer data by bankrupt retailer RadioShack, recommending that a model be adopted based on a settlement the agency reached with a failed online toy retailer.

In a letter Saturday to a court-appointed consumer privacy ombudsman, Jessica L. Rich, director of the FTC’s bureau of consumer protection, has said that the agency’s concerns about the transfer of customer information inconsistent with RadioShack’s privacy promises “would be greatly diminished” if certain conditions were met, including that the data was not sold standalone, and if the buyer is engaged in substantially the same lines of business as RadioShack, and expressly agrees to be bound by and adhere to the privacy policies.

The FTC has said that alternatively RadioShack would have to take permission from customers to transfer their data. Information of customers who do not agree would have to be purged.

In her report, ombudsman Elise S. Frejka, has recommended the sale of the personal data under conditions similar to those recommended by the FTC, with some additional provisions. The data from the wireless operators and specific mobility products is to be scrubbed.

In the first round of sale, RadioShack sold about 1,700 stores to General Wireless an affiliate of hedge fund Standard General, which entered into an agreement to set up 1,435 of these as co-branded stores with wireless operator Sprint. Some other assets were also sold in the auction.

The company asked a bankruptcy court for approval for a second auction of its assets, which included the consumer data. On May 11, RadioShack selected General Wireless as the highest and best bidder for the remaining assets, including the customer data.

RadioShack has said that credit card numbers, debit card numbers, and transaction data that are not typically found on a standard sales receipt will not be sold. Up for sale are a “contact database,” consisting of about 8.5 million opt-in email addresses, of which approximately 3.1 million were active within the last 12 months, and a “customer database,” consisting of about 67 million customer names and physical mailing address files, of which approximately 11.9 million made a purchase in the last 12 months.

As a result of court-ordered mediation, the states, the highest bidder and RadioShack have reached an agreement in principle that will resolve many of the objections and concerns raised by the state attorneys general about the sale of the customer data, according to the ombudsman report. The settlement is subject to certain consents and approvals, which are expected by the close of business on Tuesday.
